Abstract

A wavelength conversion system includes a Mach-Zehnder interferometer (2) including two optical waveguides (2A, 2B), a non-linear medium (1) provided on one (2A) of the two optical waveguides (2A, 2B), and a branching ratio adjuster (5) for adjusting the branching ratio of multiplexed light produced by multiplexing signal light and pumping light so that the powers of the signal light and the pumping light which are to be emitted from the two optical waveguides (2A, 2B) are equal to each other. The multiplexed light whose branching ratio is adjusted by the branching ratio adjuster (5) is introduced into the two optical waveguides (2A, 2B) such that the non-linear medium (1) generates phase conjugation light of the signal light and the light guided through the one optical waveguide (2A) and the light guided through the other one (2B) of the two optical waveguides interfere with each other so that the phase conjugation light is extracted as wavelength conversion light.
